To all whoni it may concern: a

Be it known that I, Simeon O. LAWIDR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovements in MoP-Wriugers; and I do here declare the fol owing to be a full, clear, an exact description of the invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wringers of the class especially designed and adapted for wringin mops, and one of the objects in view is sci itating the relative adj ustment of the wringer rol ore for effecting easv access for the mop to be wrung.

With'this and further objects in view, as will be in part hereinafter pointed out, and in part become obvious, the invention comprises certain novel constructions, combinations and arrangements of parts as herein specified and claimed.

In the accompanying drawings, Fi ire 1 is a perspective view of a wringer em odying the features'of the present invention. Fig. 2 is a similar view of the same taken from a different point of observation and showin the-pivoted roll in its raised position. ig. 8 is a view in side elevation of a fragment of the parts, a portion 9! the rece tacle being seen in vertical section. Fig. 4 is a detail, ed view of one of the foot clamps, part the olampin rod being broken away. l i 6 is a simi ar view of a fragment 0 the e ampin rod for one of the side frames. Fig. (i is a etail, fragmentary view of the pivoted end of the ivoted roller, the bearing bein seen in sect on.

Referring to t e drawingsby numerals, 1 indicates a receptacle at opposite'sides of which are arranged side frames, each consisting-of a plate 2, a clamping rod 8 and connected parts. Each plate 2, at its lower end, is provided with outstanding eyes 4 and 4-. 'lhrou h eye 4 extends the upper end portion 0 -"the rod 8, which portion is threaded and engaged by a-nut'li, abovethe eye.- The lower end'o! each rod 8 isformed with-a hack 6, which extends beneath and about the lower ilangeoff the receptacle 1 whereby threading nut' 5 downwardly will cause t e nut to engage the respective eye 4.;and 'p'ull'dow'n ,0n ate 2. "Each plate 2 is "formed withan 1o set 7,at an intermediate portienpoverhangmg the upper edge of Application tiled. larch as, 1918.:1 'lei'la1 No. saarse.

receptacle 1, and a part of the offset ortiou ispreferably struck down to form a 100k 8 extendingrinside the upper edge of receptaclel. bus the tightenin of nut 5 will cause the hooks 6 and 8 o the respective side frame to clamp the respective plate 2 firmly in place. That portion of each of plates 2 upstandmg from the offset 7 is formed with a vertica slot 9 through which extends the respective journals 10 of roller 11. The journals 10 are thus free to move up and down within the limits of slots 9, but the said journals are normally held at the up er ends of the slots by spring pressed r0 5 12, 12, each formed with an eye 13 surrounding the respective journal and extending downwardly from the eye throu h eye 4, and being surrounded by a coile spring 14 whose lower end rests upon eye 4, and whose upper end presses upwardly upon nut 15. Soul nut 15 s threaded onto the res eetive rod 12, and is adapted to be threade alon the said rod for varying the tension of tie spring 14, and thus proportionatel var ing the u ward pressure exerted y ro ler 11. Tiie eyes 13 are spaced from the respective plates 2, and the intervening portions of journals 10 are engaged by the eyes of a bad 16 by which the receptacle 1 may be lifted about. Arran ed-somewhat above and slightly at one side of roller 11 is the cooperating roller 17 whose journal 18 at one end extends beyond its bearing and is formed with a .crank rovided with an operatin handle 10. Tie other journal, 20, of rol or 17 is ournaledjn a sleeve bearing 21 which is formed with adependin eye 22 through which is assed a Eintle B. The )intle 23 is carried y eyes 2 24,'ormed at the u iper end of one of the plates 2, the intermediate eyes 24 being spaced apart for accommodating the interposed eye 22, and the end eyes 24 are spaced from the intermediate eyes for accommodating the coils 25 of a spring formediof a spring wire or red with its end portions 1, mg alon and inside of the reit active p ate 2 ant its intermediate port on, between coils 2h, looped to form a sprm linger 25". The linger 25" is so dispose that the loop surrounds the outcr end of journal 20 and exerts a downward pres- ,sure thereon when roller 17 is in operative position, so as to impart a tendency to said roller to swing upwardly on intle 23 as a pivot: whenever the roler 1 is released.

THE

.lilii finger 25"" is illustrated in Fig i ed positiontthat is to say,*the 'coils"25 liave' unwound so far as-their spring ex ansive tendency requires, and the finger ist ius left outstandingand inert, leaving the roller free for a' limited amount of pivotal movement, However, on swin ing the" roller down-" 'wardly, the upwar ly movin journal 20 will engage thefinger an in the-con tinned upward movement'of the journal will place the finger 'under such spring tension as to enable it to elevate the free end of the roller 17 when released.

The plate 2, op osite that provided with eyes 24, is forme with a preferably somewhat inclined, upwardly o ening, slot'or notch 26 whose lower end orms the bearing for the journal 18. A locking pawl 27 is disposed for closing the notch 26 and completing the bearing, and thus confining the roller 17 against upward movement except when released. Pawl 27 is pivoted at 28 to its pivot. For facility 0 plate 2 and is formed with a somewhat arcuate notch 29, corresponding in curvature to the-line of the are through which the notch travels whenthe pawl is swung upon operation, an operating lever 30 projects beyond the pivot; 28 from the pawl -20,'and an actuating spring 31 engages the lever for normally retain ing t 16 pawlv in journal-en ging osition. The spring 81 has its en ,-oppos1tethat which engages thepawlyconnected to the plate 2, and is formed with an intermediate coii32.-. 1

The lower end of each of therods 8 is preferably bifurcated, one branch of the )ifurcation extending downwardly, as at84, provided with abolt 85 which serves as a ournal for a bail-like strap 80, the end ortionsof the stra pivotally engagin tie bolt 86 and the in rmediate portion 0 the stra being bent outwardly and. rigidly engage by a tread plate 87, which serves, in operation, as a means forfacilitating the prevention of tilting of the receptucie by the placing of the foot of the operutor on said read plate. i

It is, of course, desirable to support the scrubbing receptacle or bucket spaced above the floor, and to this end I provide supportmg feet for the bucket, ireferably three in number spaced uniform y about thereceptacic. lCach of these feet consists of a foot portion proper 88, formed rcferably of a mat rod, the up crior ups anding ortion of which is rigu ly engaged by a p ate" 80 whose lower end ortion is formed in'to'gan inwardly turned wok 40, and whose upper end ortion is formed into an. outstandm eve .{wHOOiI 40 is. designed to fit, abou the lower flange clamping rod 2rhas its-loweriend; ortion and being extendingthrough theeye 41, and is hreaded and engaged by a nut 43 beneath the eye 41.. .Theupper .end portion of rod 42 is of the receptacle l anda over the v tightenbe seen, the foot is formed .into a hook 44 "extendin upper end of the rece tacle 1. ing the nut 48, it wi easily andgreadily, as well as firmly and effectively clamped in place for supportin the recegtacl'e, and may be as reu ii and quickly etached therefrom.

-In operating the wringer, assuming the arts to .be in the position indicated in Fig. ,the mop is laid over the roller 11 with the major" portion of the mop hangin down into the receptacle 1. It is noted t lat the guides 45, 45, fixed to the inner faces of the plates 2, serve to direct the mop for prevent- 1n the edges thereof from missing the ro ler. The operator then asps the handle 19 and pulls the roller 17 ownwardly until the journal 18 passes beneath the pawl 27 down the notch 26. The front edge of the pawl, above its notch 29, is rounded for causin the pawl to back off as the journal 18 is orced down the notch 26, but if the friction is found inconveniently great, the operator may depress the lever 30 and thus facilitate dpositioning the journal 18 at the lower en 0f notch 26. As soon as the journal has arrived in this position the pawl'27 springsback over the journal and effectively reventsescape thereof. It is noted here t at the incline of the notch 26 is such that journal 18 cannot escape in a vertical line, and movement of the journal in the line ofthe notch 26 is direct y in the line of the pivot.28 and must, therefore, be in the line of direct pull against the pawl, whiehthe pawl will resist without reference tothe pressure of the spring 81. It is, of course, obvious that in thus forcin r the roller 17 down u on the mop (the rol or 11 will have been orced downwardly against the tension of the sprin 14. In this position, the parts'are reacy for the wringing operation which is accomplished by manually rotating the-roller 17 in a direction for feeding the mop.upwardly, and thus exudmg the fluid from the mopand dischar ng it down into the receptacle.
